pipes, shafts, bars, etc., to be joine together without threading the parts, and it consists of a clamp comprisin two or more members applled to the a joining ends of the parts, and held in place by bolts passed through lugs on the members, the central portions of the members being made light in cross section, and of springy or compressible material so as to conform readily to the contour of the parts being held together while the lugs are spaced apart and are provided on their outer edges Awith inwardly extended Also, of other features hereinafter escribed, and specifically pointed out in the claims.

In the accompanying drawings forming a part of this specification, Figure 1 is a perspective of a two-part clamp joining two pipes together at substantially right angles to each other, Vand embodying features of my invention. Fig. 2 is a side view of the same, the front members of t-he clamp and the bolts being removed. Fi 3 is a transverse section on line 3--3 o Fig. 1. Fig. 4 is the same on line L1--11 of Fig. 1. `Fig. 5 is a perspective of a two-part clamp holding three pieces of pipes Ytogether so as to form substantially a cross. Fig. 6 is a plan view of a series of clamps, joinin 4 smaller pieces lof pipe to one large one, t e larger pipe beings own in cross section.

eferring to the drawings, A and B represent two sections of pipe or.l tubin d1sposed at right angles to each other an held together by a clamp composed of mating lmembers (J each of which is provided with lugs or ears D, having holes or (ipenin through which bolts are passe T e members-C are made of malleable iron or other springy or compressible material, and their bodies are made thin and without stiffening ribs or flanges to vpermit them when drawn together to more readily conform to the contour of the pi es or shafts to be held by the clamp. The ugs or ears D are set back some dlstance from the meeting ed es of the members C which leaves considera le space between them, and inwardly extended mating flanges F are formed on their outer edges. These anges have their inner ends joined toA the body of the member to which their respective lugs are attached, and `being placed around the edges of the lugs they greatlystrengthen them,and also permit them -to be made as thin and light as the bodies of themembers without impairin the rigidity of the lugs required tolhol the clam-p in place. They also provide recesses or cups between the lugs and around the central portions of the bolts E, intol which cement or other llin material may be placed, and be securely eld therein, to render the coupling more sanitary b completely closing the openings between t e lu s and thus preventing the accumulation lo dirt or disease germs in said openings. By this means a two part coupling is produced which is economlcal to manufacture and which will securely hold the arts of a structure together and which may be quickly and easily placed in position or removed from-any art of the structure without disturbing ot er parts, and at the same time, be made as sanitary or hygienic as a solid threaded coupling.

If preferred, the meeting edges of the members under the lugs D, and between the inner ends of the flanges F', may becut away as shown in Fig. 4; or they may be left intact to form ribs F, as shown in Fig. 3. If left intact the ribs F will add something to the rigidity of the lugs and will form a more extended surface to bear against the pi e or bar to be held. However, 1 "removed, t e meeting edges of the members C adjacent the lu s, and particularly the inner ends of the anges F which are caring surface to hold the parts securely together.

Fig. 5 re resents a form of clamp Vdesigned to ho d three pipes together substantially in the. shape of a cross, G being the main' or continuous pipe and H the two pipes held in :position thereon, while the clamp pieces ho din the same together are represented by I. he construction is the same as in Fig. 1 exce t that the clam pieces are cross shaped instead of being shaped.y

The coupling shown in Fig. 6 is intended to hold four smaller pieces of ipe O in connection with one larger piece It conoined to said edges, will provide a sufficient' sists of four sets of two part clamps Q, each adapted to hold one end of the pipes 0 in the manner already described. The inner end of each of the parts of these clamps is provided with a quadrant shaped flange R adapted to fit against the adjoining portion of the pipe P. They are also provided with side flanges rl adjoining each other through which bolts U are passed so as to hold the, clamp pieces in engagement with the pipe. In this way each of the clamps Q will hold one end of the pipes O, while the pipe P will be held by the combined pressure ofv all the flanges R. The couplings are shown in the drawing as holding pipes at substantially right angles to each other, but it is evident the angles may be varied to suit requirements and that the coupling may be made to hold pipes running parallel to' each other, or even in the same alinement.

By changing the contour of the contacting parts of the members comprising the clamp' they may be adapted to hold bars of various shapes, as well as in various relative positions to each other. If one set of lugs on a side is not sufficient to hold the parts securely together, additional lugs may be added as required. It is also preferable that the meeting edges of the members and of the flanges F should be a little apart when the members are drawn together.

What l claim is 1. In couplings for pipes, shafts, etc., a pair of mating members having bodies adapted to conform approximately to the contour of the parts to be held, mating lugs formed on lthe bodies of the members so as to stand a distance apart, inwardly extended mating flanges on the outer edges of the lugs, and means applied to the lugs to hold the members together.

2. In couplings for pipes, shafts, etc., a pair of mating members having bodies adapted to conform approximately to the contour of the parts to be held,matlng lugs formed on the bodies of the members so as to stand a distance apart, inwardly extended having their inner ends joined to the meeting edges of the members, and means applied to the lugs to hold the members together.

In couplings for pipes, shafts, etc., a pair of mating members having bodies made rial and adapted to conform to the general contour of the parts to be held, mating lugs formed on the bodies of the members so as to st-and a distance apart, inwardly extended mating flanges on the outer edges o f the lugs, and means applied to the lugs to hold the members together.

4. In couplings for pipes, shafts, etc., a pair of mating members having bodies made rial and adapted to conform to the general contour of the parts to be held, mating lugs formed .on the bodies of the members so as to stand a distance apart and have openings therein, inwardly extended mating flanges on the outer edges of the lugs around the openings, and bolts passed through the openings in the lugs to hold the members together.

5. In couplings for pipes, shafts, etc., a series of clamps each adapted to hold the end of a pipe or bar and curved flanges one on one end of each. of the clamps adapted to lit against a larger pipe or bar, and means to connect the clamps together so as to grip and hold said larger pipe or bar.

`6. In couplings for pipes, shafts,.etc., a series of clamps each adapted to hold the end of a pipe or bar and curved flanges on one end of each of the clamps adapted to fit against a larger pipe or bar, flanges with holes on the adjoining sides of the clamp parts, and bolts passed through the holes in the flanges so as to grip and hold the larger pipe or bar.
